Comparing the reaction of plant and animal cells in isotonic, hypotonic, and hypertonic solutions
Explaining how surface area, cell size, temperature, light, and pH affect cellular activities
Applying the concept of fluid pressure to biological systems. (Examples: blood pressure, turgor pressure, bends, strokes)
2. Describe cell processes necessary for achieving homeostasis, including active and passive transport, osmosis, diffusion, exocytosis, and endocytosis.
ELIGIBLE CONTENT - CHAPTER 4
• Recognize and apply the definition of homeostasis. (The ability of an organism or cell to maintain internal balance and stability by adjusting its physiological processes.)
• Recognize and apply the definition of active transport. (The movement of a substance across a biological membrane against its concentration or electrochemical gradient with the help of energy input and specific transport proteins.)
• Recognize and apply the definition of passive transport. (The diffusion of a substance across a biological membrane.)
• Recognize and apply the definition of osmosis. (The movement of water across a selectively permeable membrane.)
• Recognize and apply the definition of diffusion. (The spontaneous tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.)
• Recognize and apply the definition of exocytosis. (The cellular secretion of macromolecules by the fusion of vesicles with the cell membrane.)
• Recognize and apply the definition of endocytosis. (The cellular uptake of macromolecules and particulate substances by localized regions of the cell membrane that surround the substance and pinch off to form an intracellular vesicle.) Interactive Labs to Explore!
Cell Membranes Tutorial
This exercise introduces the dynamic complexes of proteins, carbohydrates, and lipids that comprise cell membranes. You should learn that membranes are fluid, with components that move, change, and perform vital physiological roles as they allow cells to communicate with each other and their environment. We also show that membranes also are important for regulating ion and molecular traffic flow between cells,and that defects in membrane components lead to many significant diseases.
